Hi,

I would like to know if its possible to use a PIL or a raw image as a background image.
And/Or can you help me figure out how to do it (maybe using some volume from image functinoality).
Ideally, I would like to be able to update in realtime this background image (either using a thread, or a callback)

Hi Ludovic,
The developer who could authoritatively answer your question (Greg Couch) is out this week, so I'll take a stab at it:  I don't think so. :-)  However, if your goal is to, say, make a movie with a background you provide then you could write out image files with a transparent background (described in this message: http://www.cgl.ucsf.edu/pipermail/chimera-users/2008-January/002197.html) and use most any image-processing program to compose the Chimera images with the background(s) you prefer.
Despite my flippant answer in the first sentence, I don't really know if it is possible to directly change the background.  When Greg gets back I hope he will comment on that.  Perhaps you could say more about what your ultimate goal is?
